Question 2 - Week 5 (11 marks)

TikTok Electronics manufactures an aluminium fibre tripod model “TRI-X” which sells for $1,600. The production cost computed per unit under traditional costing for each model in 2019 was as follows:

Traditional Costing	TRIX
Direct Materials	$700
Direct Labour ($20/hour)	$120
Manufacturing overhead ($38 per DLH)	$228
Total per unit cost	$1, 048

In 2019, TikTok Electronics manufactured 26,000 units of TRI-X. Under traditional costing, the gross profit on TRI-X was $552 ($1,600-$1,048). Management is considering phasing out TRI-X as it has continuously failed to reach the gross profit target of $600. Before finalizing its decision, management asks TikTok Electronics management accountant to prepare an analysis using activity-based costing (ABC). The management accountant accumulates the following information about overhead for the year ended December 31, 2019.

Activity Cost Pools	Cost Drivers	Estimated Overhead	Expected Use of Cost Drivers
Purchasing	Number of orders	$1,200,000	40,000
Machine setups	Number of setups	900,000	18,000
Machining	Machine hours	4,800,000	120,000
Quality Control	Number of inspections	700,000	28,000

The cost drivers used:

Cost Drivers	TRI-X Product
Purchase orders	17,000
Machine setups	5,000
Machine hours	75,000
Inspections	11,000

Required:
